Cleaning the reading window:
¾ Switch off the device while you are cleaning it (see Laser protection).
¾ Use a clean, soft brush to free the (glass) reading window from dust.
¾ If necessary, additionally clean the (glass) reading window with a clean, damp, lint-free
cloth and a mild, anti-static window cleaning fluid.
¾ Only clean the (plastic) reading window with a clean, damp, lint-free cloth and a mild,
anti-static window cleaning fluid.

If the reading window is scratched or damaged (cracked, broken), it must be replaced.
Please contact the SICK Service.
8.2.2 Cleaning the housing
¾ Use a soft cloth to free the housing of dust.
¾ If necessary, also clean the LEDs on the housing.
8.3 Cleaning further optical effective surfaces
Depending on the reading system equipment, additional external sensors with optical effec-
tive surfaces can be installed (e.g. photoelectric reflex switch for external reading pulsing).
Soiling of these sensors can cause incorrect switching behaviour.
¾ In order to prevent incorrect switching behaviour, remove soiling from the optical effec-
tive surfaces of the external sensors.
